private

Prepares the input by the fit by collecting the measurements on the segment &.

Parameters

gCtx	Geometry context to access the alignment of the surfaces
mCtxc	Magnetic field context to access the field map during the fit
cCtx	Calibration context to access the calibration constants from Store gate during the track state filling
seed	The seed of interest to fit

Fetch the measurements from the segment & find the first segment which has phi hits

Ensure that the drift signs from the fit are stamped onto the Uncalibrated measurements

The middle or outer segment provide the phi information. Not so easy becasue we want to Take the y0 & precision direction from the inner segment but the phi & x0 from a straight line extrapolation onto the plane

Create a surface which is shortly before the first measurement
